President Trump’s Republican allies are putting pressure on him not to entangle the U.S. militarily in Ukraine after he signaled an openness to helping craft security guarantees for the embattled nation in its war against Russian aggression.

He’s claiming he’s already ended almost one war for each month of his second term — spanning the Middle East; Africa; and Central, South and Southeast Asia. “I’ve done six wars — I’ve ended six wars,” Trump said in his meeting with Ukrainian President Volodymyr Zelensky and European leaders on Monday.
